I put all the functions in a source module into an object:
funcsrc.r contains:
funcsrc: make object! [
func1: func [] []
func2: func [] []
] ; object
This has three main advantages:
3. You are less likely to create a name clash with a Rebol function, or
another module you have included, because your names have two parts. So you
could have the functions:
funcsrc/print
funcscr/return
etc without clashing with the "global" 'print or 'return functions
2. Similarly, you can have "module-local" variables: accessible to any
function in the object, but not clashing in name with any variable declared
elsewhere:
funcsrc: make object! [
var1: 666
func1: func [] [print var1] ;; prints funcsrc/var1
func2: func [] [print var1] ;; ditto
] ; object
1. Finally, you can trash the object, and all its functions and variables in
one go:
unset 'funcsrc
You decide if that's funky or boring,
